To investigate weathering and surface characteristics of coating film on lumbers coated with Hwangchil(varnish of Dendropanax morbiftra), we carried out to investigate the resistance against discoloration, value of crack and surface characteristics of coating films on seven domestic lumbers and those of four introduced tropical lumbers. There was investigated to evaluate the properties of coating films by the varnish of Dendropanax morbifera. There was insignificant correlations between the hardness and moisture contents of each lumber treated by the varnish. There was no significant correlations between the thickness of coating film and the hardness, either. Although we investigated 11 wood species, we found only three species as resistance wood species against discoloration; Diospysos spp., Abies holophylla and Ulmus davidiana. The crack of cooing films was the largest on Zelkova serrata followed by Juglans sinensis, Cercidiphum japonicum, Teetona grands, Ulmus davidiana, Guibourtia tessmannii, Diospysos spp. and Dalbergia latifolia. However, there was no crack of coating films on the lumbers of Juniperus rigida, Prunus serrulata var. spontanea and Abies holophylla. The crack of coating film showed positive correlations with the thickness of coating film and hardness. The surface characteristics of the coating films evaluated on the basis of R;. values indicated the lumbers of Ulmus davidiana(O.l4μm), Juniperus rigida(O.15μm), Guibourtia tessmannii(O.l9μm), Dalvergia latifolia(O.20μm) and Diospysos spp.(O.20μm), Cercidiphum japonieum(O.24μm) as good species while there was insignificant differences between softwoods and hardwoods. Teetona grands, Prunus serrulata var. spontanea and Abies holophylla showed rough surface with 1.53 - 2.63 /lm of R;. values. The four kinds of rough indices(R" Rz, R.n.x and Rq) showed very low correlations with moisture contents with the correlation coefficients. The R;. and R.n.x also showed slight relationship with hardness.<br/> Keywoods : Durability, Properties, Hwangchil(varnish of Dendropanax morbifera). crack of coating films, rough surface<br/>

From late 1880s based on Chicago School Style, tall buildings have been planned and constructed in major cities by recognizing as one of the solutions to release required office spaces in limited and higher land value downtown area. Consequently, tall buildings have became a powerful expression of architecture in the modern civilization due to their huge mass and vertical spaces. This dramatic phenomenon has rapidly spread to all over the world which want to be modern city. Specially, the center of a typhoon is Asia zone as well as Korea, China and Dubai. Basically, the design of tall building needs a spacial approach to form, space, vertical movement, construction and etc comparing with low-rise buildings. Because tall buildings have a different characters for natural system such as strong wind and huge thermal effect. Hence, to achieve proper tall building facade with architectural aesthetics, the design should understand a physical phenomenon for a wind movement and a thermal appearance such as the gravity is a natural phenomenon. Therefor, the target of the study is to understand a physical phenomenon and application on tall building"s facade design. It is very important work to know how design are applied for tall building"s facade design by a wind and the sun. So, this study starts with a basic research of a general facade design topic with wind and the sun. And to get the technical data for relationship between wind force, thermal issue and glass performance which is one of the facade component part, this study will use a computer simulation method. It will give a chance to inform design methodology for tall building"s facade design before starting initial facade design. Also it will make a database to understand what facade design for wind and the sun.

Chemical components relevant to the characteristic taste of the Korean native persimmon(Diospyros kaki, Thumb) leaf tea were analyzed. Samples were processed by using three different methods ; SHT(steamed and then hot-air dried), DHT(dried in the shade, steamed and then hot-air dried) and RHT(roasted and then hot-air dried). The components analyzed were general compositions of dried perisimmon leaves and extracted solution. The composition of moisture, ash, crude lipid and total nitrogen did not show significant variation among different processing methods of the persimmon leaf tea. The contents of caffeine, tannin and vitamin C in persimmon leaf tea were in the range of 178.4~209.8μ㏖/g, 29.1~38.5㎎% and 325.3~2084.7㎎%, respectively. The vitamin C content was significantly higher in the RHT than other treatments. The contents of caffeine, tannin and vitamin C in the tea extracted solution were in the range of 101.5~130.1μ㏖/g, 15.4~25.9㎎% and 111.0~1274.3㎎%, respectively. The vitamin C in the tea solution was the highest in the RHT treatment and 61.1% of vitamin C in the leaf tea was extracted out in these processing methods. The major amino acids contained in the leaf tea were in decreasing order glutamic acid, aspartic acid, leucine and phenylalanine, these four amino acids consisting 38.9~39.8% of the total amino acid contained in the persimmon leaf tea. The major amino acids contained in the tea solution were glutamic acid, proline, histidine and arginine. Six kinds of 5'-nucleotides, CMP, AMP, UMP, IMP, GMP and hypoxanthine were detected and CMP was the most abundant component in fresh leaf, leaf tea and tea solution. The second highest 5'-nucleotides in both leaf tea and tea solutions were GMP, AMP and UMP in all processing method. The highest free sugar contained in the fresh leaf tea and tea solution was sucrose.
